' In Germany May 8, 1936 Y Claims. l (Cl. 14o-112) 'I'his invention relates to wire netting machines and more particularly to a machine for forming wire netting wherein the weft or transverse wires are welded to the warp or longitudinal wires.

5 An object of this invention is to provide a. ma-

chine for making of wire netting wherein the weft or transverse wires are tensioned during the welding operation so that the mesh formed by the weft and warp wires will be evenly spaced apart and are relieved of slack or bends so that a smooth mesh is formed by the machine.

Another object of this machine is to provide a plurality of reciprocating shuttles or wire tensioning members which are adapted to periodically place the weft wire upon the warp wires, the weft wire being welded to the warp wires and subsequently released from the shuttles so that a substantially continuous movement of the machine may be effected.

A further object of this invention is to provide pairs of reciprocating shuttle members which are mounted for rotation on a shuttle carrier in a manner whereby any desired number of shuttles may be used depending only upon the size of the mesh desired.

With the foregoing and other objects in view, the invention will be more fully described hereinafter, and will be more particularly pointed out in the claims appended hereto.

Figure 3 is a sectional View taken Ion the line 343 of Figure 1. l

Figure 4 is an enlarged vertical section partly in detail of the releasing means for one of the vshuttle members. v

Figure 5 is a fragmentary perspective view of the wire mesh formed by this machine.

Referring to the drawings wherein like numerals designate corresponding parts throughout the several views, the numeral III designates generally a pair of standards having bearings I3 at their upper ends in which a drive. shaft II is journaled. A drum generally designated as I2 is xedly secured on the drive shaft I I and comprises a pair of spaced apart plates I4 and I5. A second drum generally designated as I1 is xed to the drive shaft II in spaced relation to the drum I2 and comprises spaced apart plates I8 and I9.

A welding structure generally designated as 2| is disposed between the two drums I2 and I1 and is supported from a frame structure 22. The welding structure 2I is adapted to be vertically moved into engagement with the weft and warp wiresnat intervals by a mechanism not shown. As shown in Figure 3, the warp wires 23 are trained over a guide bar 24 which is preferably stationary and may be secured in any manner to the frame structure 22. The warp wires are drawn horizontally from the guide bar 24 through the electrodes 2|, the pulling or drawing means for the warp wires 23 being of any suitable structure, not shown.

'Ihe drum I2 has a plurality of shuttle members 25 slidable in the end plates I4 and I5, and these shuttle members 25 are adapted to move in a direction parallel with the shaft II simultaneous with the rotation of the drum I2 and the shaft II. Reciprocation of each shuttle member 25 is eiiected by means of a stationary shuttle operating member 26 which is provided with a cam groove 21 in which a roller 28 carried by the shuttle member 25 is adapted to engage. The shuttle member 25 comprises an elongated bar 29 which is provided with a longitudinally extending channel 30 therein as shown in Figure 2. The forward end of the shuttle member 25 is reduced as at 3I and a sleeve or wire guide member 32 is positioned in the nose or forward end of the shuttle member 25. A wire supply reel or drum 33 is provided for each shuttle member 25 and is rotatably supported by bracket members 34 secured to the plate I4. The reel or supply member 33 as shown in Figure 1 is positioned between the two plates I4 and I5 of the drum I2. The wire taken off of the reel 33 is threaded between a plurality of tensioning rolls 35 which are carried by the bar 29 in the groove or channel 30. The wire 36 taken from the supply reel 33 is then passed beneath a holding or gripping member 31 in the form of a toothed disk which is eccentrically mounted on a pin 3B. A spring 39 is secured at one end to a wall of the groove 30 and at the other end to the gripping member 31 and constantly holds this member 31 in engagement with the wire 36.

The drum I1 has a plurality of shuttle members 43 which are slidable in the plates I8 and I9, and these shuttle members 40 comprise an elongated bar 4I having at their inner ends a pair of wire clamping or gripping members 42.

'I'he gripping members 42 are rockably mounted on pins 43 and their gripping faces are preferably serrated as shown in Figure 2 so that the wire gripped therebetween will be rmly held against movement. The clamping members 42 are mounted within a channel or slot 44 provided in theforward end of the bar 4I. An operating rod 45 for the clamping members 42` is slidable in a bore 46 provided in the rod 4| and the forward end of the rod 45 is connected to the clamping members 42 by meansof a pair of oppositely extending links 41 so that movement of the rod 45 in one direction will move the clamping memj bers -42 into released or open position. A spring 48 is positioned in a bore 49 provided in the outer end of therod 4| andthe inner end of the spring 48 engages against a ring or collar 50 secured to the rod 45. The outer end of the spring 48 engages against a bearing 5I mounted in the rod 45.

A stationary shuttle operating member 52 is secured to the adjacent standardv I6 and is provided with a cam groove 53 in which a roller 54 usecured to each shuttle member 40 engages. An

arm or bracket 55 is secured to eachY shuttle member 4|) and a lever 56 is rockably mounted on the arm 55 and is provided at one end with a roller 51 which is rotatable thereon and which is adapted in one position to engage a stationary member 58 which operates to move the rod 45 outwardly and thereby swing the wire clamping members 4 2 intol a released position. The opposite end of the lever 56 is provided with a fork 59 having rollers 60 engaging in a grooved or channeled member 6| secured as by nuts 62 to the outer end of the rod 45.

A second releasing member 63 is secured to a slidable rod 64 carried by guide members 65. The bar 64 is preferably provided with teeth 66 which are engaged by a toothed wheel 61 mounted on a shaft 68. The shaft 68 is periodically dropped by means of an arm 69 connected to a rod 16 having a roller 1| which engages a cam member 12. The cam member 12 is mounted on a shaft 13 connected to a suitable part of the mechanism herein disclosed and so timed that when the two shuttle members are at their outermost position, as shown in Figure 1, the releasing member 63 will be moved inwardly at substantially the same time that the welding means 2| is moved into operative position.

In the use and operation of this'machine, the drive shaft is rotated by any suitable driving means and the weft wire 36 is initially threaded through the nose 32 of the weft bar 25. The weft wire 36 is preferably disposed with the end thereof projecting slightly beyond the nose 32 so that when the two shuttle members 25 and 40 are at their lowermost position, these two members will have their inner ends in substantially contacting relation, as shown in Figures 1 and -2 In this position the releasing member 58 will engage the roller V51 sol as to move the rod 45 outwardly or to the left and thus swing the wire gripping members 42 into wire receiving position. At this time both 'of the the shuttle members 25 and 40 away from each other, the pulling shuttle 40 wii1-draw the wire 36 through the shuttle 25 and the tensioning rollers will maintain this weft wire in tensioned condition at all times. When the shuttle members 25 and 46 are at their outermost and, in the present instance, at their uppermost position, the weft wire 36 is brought into contacting relation with the warp wires 23 and at this time the welding means 2| is brought into contacting relation with the warp 23 from below and with the weft 36 from above. At this time, the weft 36 is cut off by means of a pair of shears 14 which leave a small projecting portion of the wire 36 projecting beyond the inner end of the shuttle member 25. Simultaneous with the cutting off of the weft wire 36, the cam 12 moves the releasing member 63 to the right so .as to openthe clamping members 42. The two drums |2 and |1 thereafter continue their rotation and the shuttle members 25 and 40 gradually move toward each other until they reach the lowermost position at which time the inner ends of theshuttle members 25 and 40 are in a wire transferring position, as shown in Figure 2.
